  2. 21. Removal of Micropollutants from Wastewater in Aerobic Granular Sludge and Activated Sludge Systems

    Author : Cecilia Burzio; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater; Pharmaceuticals; Aerobic Granular Sludge; Microbial Community; Organic Micropollutants; Biofilm; Transformation; Sorption;

    Abstract : The presence of organic substances in the aquatic environment, such as pharmaceutically active compounds, antibiotics, and personal care products, has become a worldwide issue of increasing environmental concern. As they are present at nano- to microgram per liter concentrations, they are defined as organic micropollutants (OMPs). READ MORE

  4. 22. Adsorption and transformation of organic micropollutants in wastewater : New insights from 14C-labeling

    Author : Alexander Betsholtz; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated carbon; ozonation; Organic micropollutants; pharmaceuticals; wastewater; transformation products; biological degradation; GAC-filters; adsorption; 14C-labeling;

    Abstract : This thesis focuses on the removal of organic micropollutants and transformation products using ozone and activated carbon treatment processes. A combination of 14C-labeled and non-radiolabeled organic micropollutants was used to study aspects of micropollutant removal from novel perspectives. READ MORE

  5. 23. Physicochemical Treatment of Municipal Wastewater : From Direct Membrane Filtration to Adsorption of Organic Micropollutants

    Author : Simon Gidstedt; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direkt membranfiltrering; Granulärt aktivt kol; Avloppsvatten; Kemisk förbehandling; Mikrosilning; Direct membrane filtration; Granular activated carbon; Wastewater; Chemically enhanced primary treatment; Microsieving;

    Abstract : Pharmaceutical residues and other organic micropollutants are transported via municipal wastewater to wastewater treatment plants (WWTPs). However, current treatment processes are not designed to remove organic micropollutants, and several such compounds have been found in recipients, where they can have negative effects on aquatic organisms.

  6. 24. Risk-based management of the cost to society from infiltration and inflow to wastewater systems

    Author : Anna Ohlin Saletti; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sewer system; infiltration and inflow I I ; uncertainty; wastewater; risk management; decision support;

    Abstract : The wastewater system is an important part of our infrastructure as it protects public health and the environment. Well-functioning maintenance is essential to sustain the functionality of the system. READ MORE

  7. 25. Phosphorus recovery for fertilisers from dairy wastewater – Sustainability assessment at early stages of technology development

    Author : Marta Behjat; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental impacts; LCA; screening; phosphorus recovery; sustainability; indicator; meta-analysis; wastewater treatment; dairy wastewater;

    Abstract : A reduction in the availability of phosphate rock resources for fertiliser production coincides with an increase in phosphorus-rich dairy wastewater in Europe. This confluence of events has led to the development of technologies for phosphorus recovery from dairy wastewater and the use of the products as fertilisers in agriculture. READ MORE
